This application is a continuation application of International Application No. PCT/CN2020/127803, filed on Nov. 10, 2020, which claims priority to Chinese Patent Application No. 201911206334.3 filed on Nov. 29, 2019, the entire disclosure of which are incorporated herein by reference.
This disclosure relates to the field of testing technology, and in particular to a method, and an apparatus for checking a schematic circuit diagram and a non-transitory computer-readable storage medium.
In an actual production process, correctness of a schematic circuit diagram needs to be determined to realize rapid mass production. Therefore, the schematic circuit diagram needs to be checked to determine whether the schematic circuit diagram has problems. However, in related art, accuracy is low and costs are high for checking the schematic circuit diagram. Especially, a schematic circuit diagram of a complex system is unable to be dealt with calmly in the related art, often with problems such as missing hidden errors, long check time, and high check costs.
A method for checking a schematic circuit diagram is provided in the present disclosure, and the method includes: determining a netlist file and a bill of material (BOM) list of the schematic circuit diagram, where the schematic circuit diagram is drawn by an electronic design automation (EDA) tool; and determining whether parts in the schematic circuit diagram are in a preset part list and determining whether connection relationships among the parts meet preset connection relationships, according to the netlist file and the BOM list, to obtain a check result, where the preset part list includes standard part information of multiple parts.
According to an aspect of the present disclosure, an apparatus for checking a schematic circuit diagram is provided. The apparatus includes a processor and a memory. The memory is configured to store processor-executable instructions, where the processor is configured to implement a method for checking a schematic circuit diagram.
According to an aspect of the present disclosure, a non-transitory computer-readable storage medium is provided and configured to store computer program instructions which, when executed by a processor, are operable with the processor to implement a method for checking a schematic circuit diagram.
Other features and aspects of the present disclosure will become apparent from the following elaboration of exemplary implementations with reference to the accompanying drawings.

Various exemplary implementations, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings.

Those skilled in the art should understand that the disclosure can still be implemented without some specific details. In some examples, methods, means, elements, and circuits well-known to those skilled in the art are not described in detail in order to highlight the subject matter of the disclosure.

As illustrated in
At step S11, determine a netlist file and a bill of material (BOM) list of a schematic circuit diagram, where the schematic circuit diagram is drawn by an electronic design automation (EDA) tool.
At step S12, determine whether parts in the schematic circuit diagram are in a preset part list and determine whether connection relationships among the parts meet preset connection relationships, according to the netlist file and the BOM list, to obtain a check result, where the preset part list includes standard part information of multiple parts.
According to the above method, in implementations of the present disclosure, a corresponding netlist file and a corresponding BOM list are determined according to the schematic circuit diagram, whether the parts in the schematic circuit diagram are in the preset part list is determined and whether connection relationships among the parts meet the preset connection relationships is determined, according to the netlist file and the BOM list, to check the schematic circuit diagram and obtain the check result. The method for checking the schematic circuit diagram proposed in the implementations of the present disclosure has characteristics of simplicity and accuracy, which can check the schematic circuit diagram quickly and accurately, so as to avoid missing hidden errors and reduce costs in checking, thereby improving check efficiency of the schematic circuit diagram.
It should be noted that in the present disclosure, implementations of determining the netlist file and the BOM list of the schematic circuit diagram at step S11 are not limited. Those skilled in the art can determine the netlist file and the BOM list of the schematic circuit diagram in a variety of manners, such as importing the schematic circuit diagram into an EDA software and exporting the netlist file and the BOM list of the schematic circuit diagram by the EDA software.
In the implementations of the present disclosure, part information of the circuit diagram is determined according to the netlist file and the BOM list exported from the schematic circuit diagram, which is more accurate than part information directly obtained from the schematic circuit diagram in related art. In addition, determining the part information according to the netlist file and the BOM list is universal and has low requirements for sources of the schematic circuit diagram, as long as the schematic circuit diagram is drawn by the EDA software.
In a possible implementation, the preset part list and the preset connection relationships can be configured as a standard file in advance. In an example, they can be stored in a database. When the netlist file and the BOM list of the schematic circuit diagram are determined at step S11, the preset part list and the preset connection relationships can be obtained from the database to check the parts of the schematic circuit diagram and the connection relationships among the parts. The preset part list can include standard part information of all or part of parts in a part library on which a circuit design is based, such as standard part information of parts commonly used by circuit design manufacturers. The preset connection relationships can include standard connection relationships of some common parts, all or part of specific connection relationships in a checked schematic circuit diagram, etc.
Reference can be made to
As illustrated in
In the implementations of the present disclosure, the preset part list and the preset connection relationships are stored in the database to be invoked when the schematic circuit diagram is needed to be checked, such that multiple schematic circuit diagrams can be checked in parallel. When the multiple schematic circuit diagrams need to be checked in parallel, parallel tasks can be established. For each task, a preset part list and preset connection relationships can be obtained independently from the database and a schematic circuit diagram can be checked independently, which can improve efficiency and speed of checking circuits.
In the implementations of the present disclosure, whether the parts in the schematic circuit diagram are in the preset part list can be determined in multiple manners, and the following will give an exemplary introduction.
In a possible implementation, the standard part information can include standard part types of parts, and determining whether the parts in the schematic circuit diagram are in the preset part list according to the netlist file and the BOM list at step S12 includes: determining a part type of each part in the schematic circuit diagram according to the BOM list; and determining that a part exists in the preset part list, in a case that a standard part type identical with a part type of the part exists in the preset part list.
According to the above method, in the implementations of the present disclosure, the part type of each part in the schematic circuit diagram can be determined according to the BOM list, and whether the part exists in the preset part list can be simply and quickly determined by matching the part type of the part with the standard part type.
In an example, the netlist file of the schematic circuit diagram can include a part number, a pin number (PinNO), a pin name (PinName), a pin count (PinCount), a network name (NetName), etc., of each part. The BOM list can include a part number and a part type (PartType) of each part. Part numbers of identical parts are identical in the netlist file and the BOM list.
In an example, a network name can be used to indicate connection relationships among a pin of the part and pins of other parts. In general, keywords in the network name and the pin name are identical. For example, a pin name and a network name of a clock pin of a subscriber identification module (SIM) card generally include “SIM_CLK”, and a pin name and a network name of an input and output pin generally include “SIM_IO”, etc.
In the present disclosure, naming manners of the pin name and the network name are not limited. In an example, a pin can be named as “interface-function_signal-category”. In this way, an interface category and a signal category that a pin belongs to can be determined according to the pin name. For example, for a pin name “SIM_CLK”, an interface that the pin belongs to can be determined as a SIM card interface, and the pin is configured to transmit a clock signal. Of course, it should be understood that the above description of the naming manners of the pin name is exemplary and should not be regarded as a limitation on the present disclosure. Those skilled in the art can set a category of the pin name and a category of the network name as needed, which is not limited by the present disclosure.
In a possible implementation, the standard part information can further include part numbers, and determining whether the parts in the schematic circuit diagram are in the preset part list according to the netlist file and the BOM list at step S12 further includes: obtaining a part number according to the part type of the part, in a case that the standard part type identical with the part type of the part does not exist in the preset part list; determining a pin name and a network name of the part in the netlist file according to the part number; and determining a target part type of the part in the standard part information according to the pin name and the network name of the part.
In an example, part numbers have a one-to-one correspondence with part types in the BOM list, part numbers have corresponding relationships with pin names, network names, and pin counts in the netlist file. Therefore, in the implementations of the present disclosure, the part number of the part can be obtained according to the part type of the part, and the pin name and the network name of the part can be determined in the netlist file after the part number of the part is obtained.
In some cases, due to differences of each manufacturer and each technician, part types of parts in each schematic circuit diagram may be different. For example, an identical part may have different part types without an agreement, and in this case, whether a part is in the preset part list cannot be determined according to a part type different from the standard part type. Therefore, in the implementations of the present disclosure, the target part type of the part can be determined in the standard part information according to the pin name and the network name of the part. The following is an exemplary introduction to possible implementations that the target part type of the part can be determined in the standard part information according to the pin name and the network name of the part.
In a possible implementation, the standard part information includes standard pin names and standard network names of the parts, and determining the target part type of the part in the standard part information according to the pin name and the network name of the part includes: obtaining a keyword in at least one of the pin name or the network name of the part; and determining a standard part type of a part corresponding to a matched standard pin name and/or a matched standard network name in the preset part list as a target part type of the part, in a case that a standard pin name and/or a standard network name matching the keyword in at least one of the pin name or the network name of the part exists in the preset part list.
According to the above method, in the implementations of the present disclosure, when an original part type of the part (a part type obtained from the BOM list) cannot be matched, the keyword in at least one of the pin name or the network name of the part can be used to match to determine whether the part is in the preset part list. When the standard pin name and/or the standard network name matching the keyword in at least one of the pin name or the network name of the part exists in the preset part list, a present part can be determined to be in the preset part list, and in the implementations of the present disclosure, the standard part type of the part corresponding to the matched standard pin name and/or a matched standard network name in the preset part list can be determined as the target part type of the part.
In an example, if the pin name and the network name of the part include a keyword “SIM”, when a corresponding part matching “SIM” in the preset part list is a SIM part and its standard part type is “SIM_Card”, the part can be determined to be the SIM part and the target part type can be determined to be “SIM_Card”.
When the keyword in at least one the pin name or the network name of the part is not matched in the preset part list, the present part can be determined to be not in the preset part list, which can be recorded in the check result as warning information in this case.
Of course, after a corresponding standard part type is queried by fuzzy matching according to the keyword in at least one of the pin name or the network name of the part, next determination can further be performed. For example, a pin count of the part can be obtained from the netlist file and a pin count of a matched part can be obtained from the preset part list. When the pin count of the part is equal to the pin count of the matched part, the present part can be determined to be in the preset part list. According to such a method, in the implementations of the present disclosure, reliability of checking can be improved and a more accurate check result can be obtained.
In a possible implementation, determining the target part type of the part in the standard part information according to the pin name and the network name of the part further includes: determining that the part does not exist in the preset part list, in a case that the standard pin name and/or the standard network name matching the keyword in at least one of the pin name or the network name of the part does not exist in the preset part list.
It should be noted that although the present disclosure gives an exemplary description of determining whether the part exists in the preset part list in the order of part type matching followed by keyword matching, the present disclosure is not limited thereto. In some implementations, the part type matching can be performed first. When whether the part is in the preset part list cannot be determined by the part type, keyword matching can be determined next. When whether the part exists in the preset part list cannot be determined according to the keyword in at least one of the pin name or network name of the part, a check result can be recorded. Of course, the keyword matching can be determined before the part type matching.
Reference can be made to
As illustrated in
Possible implementations of determining whether the parts are in the preset part list have been described above and an exemplary introduction of whether connection relationships of each part satisfy the preset connection relationships is given below.
In a possible implementation, the parts in the schematic circuit diagram include a main chip and other parts coupled with the main chip, and determining whether the connection relationships among the parts meet the preset connection relationships at step S12 includes: determining the main chip according to the preset part list and part types of the parts in the BOM list; determining whether an actual connection object of an interface to be checked of the main chip is identical with a preset connection object of the interface to be checked of the main chip in the preset connection relationships; and determining whether an actual connection relationship between each pin of the interface to be checked of the main chip and each pin of the actual connection object is identical with a preset connection relationship between each pin of the interface to be checked of the main chip and each pin of the preset connection object, in a case that the actual connection object is identical with the preset connection object.
According to the above method, in the implementations of the present disclosure, the connection relationships of each pin of a specified interface to be checked can be determined, to determine whether the connection relationships among each pin of the main chip and the pins of other parts meet the preset connection relationships.
In a schematic circuit diagram, there are numerous parts, which can be divided into different categories. For example, a part that provides core functions (abundant and complex functions) can be a main chip (such as a SIM part, a Bluetooth chip, etc.), and a part with a single function is an ordinary part (i.e., other parts). In the implementations of the present disclosure, the main chip can be determined according to the part types of the parts (e.g., the main chip in the schematic circuit diagram can be determined by matching the part types in the BOM list with a main chip in the preset part list).
For different products, objects to be checked in schematic circuit diagrams can be different. For example, assuming that a main chip includes a translator interface, a camera interface, and a display interface, if a product has a single function which only needs to implement a translator without a display and a camera, the display interface and the camera interface do not need to be checked, and only the translator interface needs to be checked.
In the implementations of the present disclosure, an interface to be checked is specified and connection relationships of the interface to be check are checked, such that interfaces that do not need to be checked can be avoided checking and check efficiency can be improved. If the interface to be checked is not specified, in this example, the display interface and the camera interface will be checked according to a default check flow, which obviously wastes resources and costs. Therefore, in the implementations of the present disclosure, costs and resources can be reduced, while check efficiency can be improved.
In the implementations of the present disclosure, targeted check can be performed by specifying the interface to be checked, so as to meet different needs and increase flexibility and environmental adaptability.
In a possible implementation, determining whether the actual connection object of the interface to be checked of the main chip is identical with the preset connection object of the interface to be checked of the main chip in the preset connection relationships includes: determining a pin name and a network name of the interface to be checked in the netlist file and the BOM list, where the network name is used to indicate connection relationships among a pin of a part and pins of other parts; and determining the actual connection object according to the pin name and the network name of the interface to be checked, to determine whether the actual connection object is identical with the preset connection object in the preset connection relationships.
According to the above method, in the implementations of the present disclosure, the actual connection object of the interface to be checked can be conveniently and quickly determined according to the pin name and the network name of the interface to be checked, such that check efficiency can be improved.
In the present disclosure, implementations of how to determine the actual connection object according to the pin name and the network name of the interface to be checked are not limited, and those skilled in the art may can select a corresponding method as needed.
In an example, a connection relationship of the interface to be checked can be determined according to the pin name and the network name, and the actual connection object of the interface to be check can be determined according to the connection relationship.
The pin name and the network name can include an interface function category and a signal category of each pin of the interface to be checked. Therefore, the connection relationship of the interface to be checked can be determined according to the pin name and the network name, so as to determine the actual connection object according to the connection relationship. For example, if a pin name of a pin of the interface to be checked includes “SIM_CLK”, the pin can be determined to belong to an interface of a SIM part, and the actual connection object of the interface to be checked can be determined to be the SIM part.
Of course, the above description is exemplary and should not be regarded as a limitation on the present disclosure.
In a possible implementation, the preset connection object can be determined not only according to the preset connection relationship in the database, but also according to the pin name and the network name of the part in the preset part list or the netlist file of the schematic circuit diagram.
In an example, an interface category of the interface to be checked, i.e., the connection object of the interface to be checked, will be generally written into the pin name and the network name. For example, when the interface to be checked is defined to be coupled with the SIM part, the pin name and the network name of the interface to be checked will include a keyword “SIM”. Therefore, the preset connection object of the interface to be checked can be determined according to the pin name and the network name of the interface to be checked.
In a possible implementation, the method further includes: in prior to determining whether the actual connection relationship between each pin of the interface to be checked of the main chip and each pin of the actual connection object is identical with the preset connection relationship between each pin of the interface to be checked of the main chip and each pin of the preset connection object, determining whether an input/output relationship between each pin of the interface to be checked and each pin of the actual connection object of the interface to be checked is identical with a preset input/output relationship in the preset connection relationships.
For example, the pin of the interface to be checked may be of an output category or an input category, such as a clock pin CLK. When the main chip outputs a clock signal, a CLK pin of the interface to be checked is of an output category, correspondingly, a CLK pin of the actual connection object should be of an input category. Assuming that the CLK pin of the interface to be checked is coupled with a pin of an output category (the CLK pin of the interface to be checked needs to receive a signal), or the CLK pin of the actual connection object is coupled with a pin of an input category (the CLK pin of the actual connection object needs to output a signal), an error is indicated to occur.
When a check result of one pin of the interface to be checked is obtained (including correct and wrong ones), a check process of the next pin of the interface to be checked can be performed. When all pins of the interface to be checked are checked, a check process of the next interface can be performed. When all interfaces are checked, a check result can be output.
The following is an exemplary introduction to checking the connection relationship of the interface to be checked.

According to the above method, in the implementations of the present disclosure, the schematic circuit diagram can be quickly and accurately checked to obtain the check result, such that check efficiency of the schematic circuit diagram can be improved, and time and labor costs can be saved.
